Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleotide sequences (target sequences) by hybridization. Genomic library comprises large number of genes in the form of different nucleotide sequences of DNA fragments and they can be selected with the help of DNA probes.

So, the correct option 'DNA probes'.

Hot spots of biodiversity means

  1. Areas of earth that contain many endemic species

  2. Species serves as proxy for entire community in particular areas

  3. Species in particular niche/area

  4. Species diversity at particular area
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ecological hot spots are large areas of Earth's land surface which have high concentrations of plant endemism and also experience high rates of habitat loss. In India, 4 ecological hot spots are presently identified. The Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland constitute the biodiversity hot spots in our country. One of the major features of these places is the presence of numerous endemic species.

So, the correct answer is 'Areas of earth that contain many endemic species'.

Hot spots are the examples of 

  1. Insitu conservation

  2. Exsitu conservation

  3. Wildlife protection

  4. Water conservation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • A biodiversity hotspot is an area which has lost at least 70 per cent of its primary native vegetation 

  • It contains at least 1,500 species of vascular plants which are endemic.

  • There are currently 36 recognized biodiversity hotspots.

  • These are Earth’s most biologically rich yet threatened terrestrial regions.

  • The hotspots provide crucial ecosystem services for human life, such as provision of clean water, pollination and climate regulation.
  • Conservation in the hotspots promotes sustainable management of these essential natural resources and supports economic growth, which also reduces drivers of violent conflict.
  • So, the answer is in-situ conservation.

Where are Hotspots of biodiversity in India?

  1. Western ghats, Eastern ghats, Indo Burma

  2. Indo Burma, Eastern ghats and Sri Lanka Himalayas

  3. Western ghats & Sri Lanka, Indo Burma and Himalaya

  4. Eastern ghats & Sri Lanka, Indo Burma
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction.
  • The term biodiversity hotspot specifically refers to biologically rich areas around the world that have lost at least 70 per cent of their original habitat.
  • There are 34 biodiversity hot spots across the globe, among which three occur in India such as the Western Ghats & Sri Lanka, Indo-Burma (North East India) and the Himalayas.
  • Hence Western ghats & Sri Lanka, Indo Burma and Himalaya are Hot Spots of biodiversity in India.ervo
  • So, the correct answer is 'The Western Ghats & Sri Lanka, Indo Burma and Himalaya'.

Ecological hot spots present in India are

  1. One

  2. Two

  3. Three

  4. Four
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ecological hot spots are large areas of Earth's land surface which have high concentrations of plant endemism and also experience high rates of habitat loss. In India, 4 ecological hot spots are presently identified. The Himalayas, the Western Ghats, the Indo-Burma region and the Sundaland constitute the 4 biodiversity hot spots in our country. One of the major features of these places is the presence of numerous endemic species.

So, the correct answer is 'Three'.

According to, May's global estimates how many species of plants and animals, respectively, are yet to be discovered and described from India? 

  1. 50,000 and 90,000

  2. 3,00,000 and 90,000

  3. 3,00,000 and 1,00,000

  4. 1,00,000 and 3,00,000
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

If we accept May's global estimates only 22% of the total species have been recorded so far. If May's proposal for discovery of new species is accepted then there are probably more than 1,00,000 plant species and more than 3,00,000 animal species yet to discovered and described.

Vertical distribution of different species occupying different levels in dense vegetation is called.

  1. Stratification

  2. Species composition

  3. Standing crop

  4. Trophic structure

A Correct answer
Explanation

Vertical distribution of different species occupying different levels is called stratification. For example, trees occupy top vertical strata or layer of a forest, strubs the second and herbs and grasses occupy the bottom layers.

Fill in the blanks with the most appropriate option. 
The values of z lies in the range of _______ regardless of the taxonomic group or the region.

  1. 0.1 to 0.2

  2. 0.3 to 0.8

  3. 0.1 to 1.0

  4. 0.6 to 1.8
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alexander Von Humboldt observed that within a region richness increased with increased explored area, but only upto a limit. If a graph is plotted between species richness and area then we get a rectangular hyperbola. ON a log scale, the relationship becomes linear (straight line) and is described by the equation,

log S = log C + Z log A
where, S = species richness, Z = slope of the line (regression coefficient)
A = are and C = y-intercept
The value of Z ranges between 0.1 and 0.2 irrespective of the taxonomic group for a small area. But, if a larger area is taken into account then the slope is steeper and the vale of Z ranges between 0.6 and  1.2.
So the correct option is '0.1 to 0.2'.
